The above-mentioned EEPROM as storage part can be replaced by flash memory.
The anti-theft system 10 of this embodiment is essentially above structure, below with reference to diagram of circuit its action is described.
At first, with reference to the diagram of circuit of Fig. 6 to the login of the 2nd heading code 2 in the storage part 52 of the storage part 48 that is stored in anti-joyride device 18 or upgrade to handle and describe.
Below the login of the 2nd heading code ID2 in Shuo Ming the storage part that is stored in anti-joyride device 18 52 or renewal are handled, and can improve the theftproof performance with the vehicle under the situations such as remote-control key 21 and ignition key 14 and anti-joyride device 18 replacings because of the malice third party.
Therefore, in step S1, remote-control key 12 is carried out authentication processing.That is, the CPU60 of anti-joyride device 18 receives the 1st heading code ID1r that reads and be sent out out from the storage part 34 of remote-control key 12 with receiving loop 42 by antenna 40.The 1st heading code ID1r that CPU60 will receive and the 1st heading code ID1r that reads from oneself storage part 51r check.
Then, in step S2, ignition key 14 is carried out authentication processing.That is, CPU60 is changed to on-state according to the key insertion detection signal Sin that key inserts detector switch 30, detects ignition key 14 and has been inserted in the key cylinder 28.At this moment, CPU60 sends energizing signal by sending receiving loop 43 and 41 pairs of ignition keys 14 of loop antenna.And the transponder beacon 33 that receives the ignition key 14 of energizing signal will send to anti-joyride device 18 from the 1st heading code IDt that the storage part 32 of oneself is read.The 1st heading code IDt that CPU60 will receive and the 1st heading code IDt that reads from storage part 51t check.
Arbitrary in step S1, S2 checks under the situation of success (result who checks is OK), in other words, between the 1st heading code IDr in being stored in remote-control key 12 and anti-joyride device 18 respectively or be stored in respectively under the situation consistent with each other between the 1st heading code IDt in ignition key 14 and the anti-joyride device 18, in step 3, CPU60 judges according to ignition lock signal Sig whether ignition lock 26 has been switched on the igniting control position.
Under the situation that is in the igniting control position, in step S4, CPU60 reads the 3rd heading code ID3 by order wire 16 from the storage part 63 of the 3rd device 24, and it is checked with the 3rd heading code ID3 that reads from the storage part 53 of oneself.In addition, be in the igniting control position situation under, from storage battery 27 to engine control unit 22 supply capabilities.
Under the situation of checking success (checked result is OK) of step S4, in other words, stealing under the 3rd heading code ID3 of device 18 in installing with the 3rd situation consistent with each other, next when being stored into respectively, in step S5, CPU60 judges the checked result of the 2nd heading code.
In step S5, at first, CPU60 sends the transmission requirement of hatted code R to engine control unit 22 by order wire 16.Receive engine control unit 22 that the transmission of hatted code R requires and drive random number generators 65 generating hatted code R, and the hatted code R that generates is sent to anti-joyride device 16 by order wire 16.Receive the CPU60 of the anti-joyride device 18 of hatted code R, take place the function f (A, x) with sign indicating number by the authentication that storage part 54 stores with this hatted code R that receives with from the 2nd heading code ID2 substitution that the storage part 52 of oneself is read, obtain functional value (result of calculation) V{V=f (ID2, R) }.CPU60 sends this result of calculation V by order wire 16 from anti-joyride device 18 to engine control unit 22.Hatted code R that engine control unit 22 generates and sends oneself and the 2nd heading code ID2 substitution of reading from the storage part 62 of oneself are taken place the function f (A, x) with sign indicating number by the authentication that storage part 61 stores, obtain functional value (result of calculation) V{V=f (ID2, R) }, check from the result of calculation V that anti-joyride device 18 receives with this result of calculation V and by order wire 16.Engine control unit 22 sends checked result (OK or NG) to anti-joyride device 18.In the checked result that sends is under the situation of OK, and the 2nd heading code ID2 becomes in the storage part 62 of the storage part 52 of anti-joyride device 18 and engine control unit 22 state that login respectively has same code, and the 2nd heading code ID2 checks success (checked result is OK).
So, with sign indicating number function f (A, x) takes place by deposit identical authentication in anti-joyride device 18 and engine management system 22, in the collation process of the 2nd heading code ID2 of step S5, itself need not send the 2nd heading code ID2 by order wire 16, and theftproof performance is good.In the success of checking of key (remote-control key 12 or ignition key 14), in step S5,,, need not to carry out the login process of the 2nd heading code ID2, so processing finishes owing to be judged as normal logging status to the checking under the case of successful of the 2nd heading code ID2.
On the other hand, under the situation of having changed engine control unit 22, in other words, under the mutual inconsistent situation of result of calculation V, because it is mutually internally inconsistent that CPU60 can judge the 2nd heading code ID2 from the checked result (NG) that receives, so, next, for login, the renewal of anti-joyride device 18 being carried out the 2nd heading code are handled, at first in step S6, CPU60 judges whether the drg of parking have been carried out the operation (the pattern input that no standard is arranged is judged) of regulation from the detection signal Sp as the processing switch 44 of weighting important document.
In step S6, thereby under the situation of the operation input that the pattern of input regulation is stipulated, in step S7, the CPU60 of anti-joyride device 18 requires engine control unit 22 to send the 2nd heading code ID2 by order wire 16.
Like this, because the transmission of the 2nd heading code ID2 requires to be set to, only could export under as the condition of weighting important document, so the theftproof performance height checking of the 3rd heading code ID3 of step S4 for OK and with the predetermined processing of step S6.
In step S7, when the CPU60 of anti-joyride device 18 required engine control unit 22 to send the 2nd heading code ID2, in step S8, CPU60 starting timing time (during the timing) be a specified time, is 300[ms herein] the 2nd heading code reception watch-dog timer.
And, when engine control unit 22 when step S7 has received from the requiring of transmission the 2nd heading code ID2 of the CPU60 of anti-joyride device 18 later on, it can read the 2nd heading code ID2 from the storage part 62 of oneself, and sends the 2nd heading code ID2 by order wire 16 to anti-joyride device 18.
In the case, in step S9, anti-joyride device 18 judges whether received the 2nd heading code ID2 by order wire 16.
At 300[ms] with under the interior situation that receives the 2nd heading code, in step S11, the CPU60 of anti-joyride device 18 is according to the 2nd heading code ID2 that is read and receive from the storage part 62 of engine control unit 22, rewrites the data content in (renewal) oneself storage part 52.
In this upgrade to handle, the CPU60 of anti-joyride device 18 deletion was stored in the 2nd old heading code ID2 in oneself the storage part 52, write the 2nd new heading code ID2 that (login) receives from engine control unit 22 in this oneself storage part 52.
By the 2nd heading code ID2 of the storage part 52 of this login process or the anti-joyride device 18 that upgrade to handle produces, become the consistent code of the 2nd heading code ID2 with the storage part 62 of engine control unit 22.
In the case, in step S12, login the demonstration of normal termination and handle, finish entire process.
On the other hand, in step S9, do not receive the 2nd heading code ID2, and in step 10, passed through 300[ms as specified time] situation under, CPU60 think the login operation normally do not carry out, in step 13, carry out the demonstration of abnormal end and handle, finish entire process.
In the demonstration of normal termination is handled, display lamp 38 is represented login, (is for example upgraded normal luminous demonstration, send green light or login, the normal literal demonstration of renewal occur), in the demonstration of abnormal end is handled, display lamp 38 is represented to login, the luminous demonstration of update anomalies (for example, the literal that sends red light or login, update anomalies occur shows).
In addition, though in the above-described embodiment, be when re-engining control setup 22, upgraded the 2nd heading code ID2 in the storage part 52 that is stored in anti-joyride device 18 sides, but also can be shown in the diagram of circuit of Fig. 7, be updated to the 2nd heading code ID2 in the storage part 52 that is stored in anti-joyride device 18 with being stored in the 2nd heading code ID2 in the storage part 62 of engine control unit 22.
In the processing of the diagram of circuit of this Fig. 7, the processing of step S1～S6 is identical with the processing of diagram of circuit shown in Figure 6, thereby omits its explanation.
In the case, in step S107, CPU60 sends the more new demand of the 2nd heading code ID2 by 16 pairs of engine control units of order wire 22.
In addition, because the transmission of the more new demand of the 2nd heading code ID2 also is set at, only in steps among the S4 to the 3rd heading code ID3 check for OK and with the predetermined processing of step S6 as just exporting under the condition of weighting important document, so theftproof performance is higher.
In step S107, when requiring engine control unit 22 to upgrade the 2nd heading code ID2, in step S108, CPU60 starting timing time (during the timing) be a specified time, is 300[ms herein] login renewal watch-dog timer.
Then, in step S109, CPU60 judges that whether having received expression from engine control unit 22 upgrades the answer that preparation has finished.
Not receiving under the situation of above-mentioned answer, shown in step S110, carry out this judgement ,] up to the timing time through login, renewal watch-dog timer, i.e. 300[ms always.
In that to have passed through timing time be 300[ms] situation under, CPU60 thinks that the login operation normally do not carry out, and handles so carry out the demonstration of the abnormal end of above-mentioned step S13, finishes all to handle.
Relative therewith, when in step S109, CPU60 upgrades under the situation of preparing the answer that finished with interior having received at timing time, it will read the 2nd heading code ID2 in the storage part 52 that is stored in oneself in step S111, and will send the 2nd heading code ID2 by order wire 16 to engine control unit 22.
After this, in step S112, CPU60 judges whether received expression login (renewal) answer of normal termination from engine control unit 22.
Not receiving under the situation of above-mentioned answer, in step S113, judge whether to have received to login and wait expression that the unusually also answer of end has taken place.
Under the situation of the answer that does not receive abnormal end, in step S110, judge the 300[ms that whether has passed through as the timing time of login, renewal watch-dog timer], as yet not under the situation of process, after the transmission again of the affirmation of the determination processing of having carried out step S109 and the 2nd heading code ID2 among the step S111 is handled, in step 112, CPU60 judges whether received expression login (renewal) answer of normal termination from engine control unit 22 once more.
When the answer that in this step S112, does not receive login (renewal) normal termination, and in step S113, received under the situation of answer of abnormal end, perhaps in step S113, do not receive the answer of abnormal end, and in step S110, passed through 300[ms as specified time] situation under, CPU60 thinks that logining operation does not normally carry out, thereby the demonstration of carrying out abnormal end in step S113 is handled, and finishes all to handle.
Relative therewith, when in step S112, receiving and being illustrated in specified time is 300[ms] under the situation with the interior answer of normally having carried out logining (renewal), CPU60 carries out the demonstration of the login normal termination identical with above-mentioned step S12 to be handled, and finishes all to handle.In this case, being stored in the 2nd heading code ID2 in the storage part 62 of engine control unit 22 is updated (rewriting) and is the 2nd heading code ID2 in the note portion 52 that is stored in anti-joyride device 18.
More than to the 2nd heading code ID2 in the storage part 52 that is stored in anti-joyride device 18, or be stored in the login of the 2nd heading code ID2 in the storage part 62 of engine control unit 22 or upgrade to handle and be illustrated.
Following diagram of circuit with reference to Fig. 8～Figure 10, the collation process (code authentication processing) of various heading codes is described, the purpose of these collation process is that decision was that it is worked on, and the driving engine that has started is stopped after decision started working driving engine by ignition key 14.And this code authentication processing is the processing that must carry out when driving engine is started working.The part of its content and above-mentioned login, renewal are handled and are repeated.The counterweight complex point carries out simple declaration.
Fig. 8 and Fig. 9 are that Figure 10 is the diagram of circuit by the performed code authentication procedure of the not shown CPU of engine control unit 22 by the diagram of circuit of the program of the performed code authentication processing of anti-joyride device 18 (CPU).And, since too numerous and diverse, so will not omit can not cause indeterminate exceeding as the CPU of program subject of implementation.
At first, in step S21, whether utilize key to insert signal Si detection ignition key 14 has inserted in the key cylinder 28 and 30 ons of key insertion detector switch, when detecting on, in step S22, the transponder beacon 33 of inwardly ensconcing in the ignition key 14 sends energizing signal, carries out the authentication processing to ignition key 14 same with above-mentioned step S2.And, after having sent energizing signal, in step S23, make the 1st heading code check time monitoring time meter (500ms time meter) and pick up counting.
That is, anti-joyride device 18 is the transponder beacon 33 in the plant ignition key 14 in the starting, and sends energizing signal from loop antenna 41.Energizing signal supplies with electric power to transponder beacon 33, and the 1st heading code ID1t that therefore transponder beacon 33 will be stored in the storage part 32 sends.
In step S24, S25, the 1st heading code ID1t that anti-joyride device 18 will receive from transponder beacon 33 and the 1st heading code ID1t that the storage part 51t from oneself reads check, under the consistent situation of (OK), change step S26 in the timing time of the aforementioned 500ms time meter after this checked result is sending energizing signal.
In step S26, detect ignition key 14 by ignition lock signal Sig and whether be switched on igniting connection (IGN ON) position, when not detecting signal, in step 27, utilize key to insert signal Sin and judge whether ignition key 14 is pulled up.Under ignition key 14 quilt situations about pulling up, end process.Promptly, in step S24, S26, even the 1st heading code ID1 checks unanimity, but detect that ignition lock 26 is not set as that igniting is connected, ignition key 14 by the situation of extracting from key cylinder 28 under, though the intelligent anti-theft function is not disengaged, but because abnormal condition do not take place, so direct termination routine.
In step S26, be switched to when ignition lock under the situation of igniting control position, in step S28, making timing time is 2[s] the 3rd heading code check time monitoring time meter (2s time meter) and pick up counting.And, at this moment, because to engine control unit 22 supply capabilities, so when the user went to the starting position with ignition lock 26, driving engine was started by ignition device 71 and Fuel Injection Device 72.
Then, in step S29, CPU60 requires signal by storage part 63 transmissions the 3rd heading code transmission of 16 pairs the 3rd devices 24 of order wire, just requires the signal of its transmission (reading processing) the 3rd heading code ID3.
In step S30, the 3rd heading code ID3 that this transmission requirement of response is read and transmitted by order wire 16 reception from the storage part 63 of the 3rd device 24 checks with own the 3rd heading code ID3 that reads from storage part 53, under the situation of (OK) with interior unanimity when timing concluding time (specified time) that this checked result begins from the timing of 2 seconds time meters of step 31 again, change step S32 over to.
In step 32, for checking of the 2nd heading code ID2 that stores separately, anti-joyride device 18 sends hatted codes by 16 pairs of engine control units of order wire 22 and sends and require signal, just requires to send the signal of hatted code R (random number).
In step S33, S34, when the timing from the 2s time meter begins, when receiving hatted code R by order wire 16 at the appointed time, the hatted code R that will in step S33, receive and being stored in the function f (A, x) that the 2nd heading code ID2 substitution in the storage part 52 stores by storage part 54, computing function value f (ID2, R), in step S35, result of calculation V (V=f (ID2, R)) is sent to engine control unit 22 by order wire 16.
After this, in step 37,38, wait for by order wire 16 and receiving according to aforementioned functions value f (ID2 from engine control unit 22, R) checked result of the 2nd heading code ID2, when timing since 2 seconds time meters, when in the timing concluding time (specified time), receiving the signal (checked result OK) of the checked result unanimity of representing the 2nd heading code 2, be judged as the intelligent anti-theft function and removed by proper solution, and end of program.
On the other hand, when following four kinds of situations occurring, be judged as in step S39 that stolen or fault etc. take place is unusual and the intelligent anti-theft function is not disengaged, by display lamp 38 display abnormality states, and termination routine: the 1st kind of situation is because of the checked result of the 1st heading code ID1 of step S24 is not consistent at the appointed time, and the situation that timing finishes in step S25; The 2nd kind of situation is because of the checked result of the 3rd heading code ID3 of step 30 is not consistent at the appointed time, and the situation that timing finishes in step S31; The 3rd kind of situation is because of not receiving hatted code R among the step S33 at the appointed time, and the situation that timing finishes in step 34; And then the 4th kind of situation is because of the checked result that do not receive the 2nd heading code ID2 in step S37 at the appointed time is the signal of OK, and the situation that timing finishes in step S38.
In addition, in the 1st kind of situation, under the situation that timing finishes in step 25, because ignition lock 26 is not in the ignition lock control position, so driving engine is inoperative.In addition, in the 2nd～4th kind of situation, under the situation that timing finishes in step S31, S34, S38, after setting up in the judgement of step S26, before timing finishes, ignition lock 26 is returned back to the starting position, and when driving engine was started by ignition device 71 and Fuel Injection Device 72, driving engine was stopped under the control of engine control unit 22 as described later; And after timing finished, even ignition lock 26 is returned back to the starting position, driving engine can not start yet.
In addition, also can in step S39, show the reason that the intelligent anti-theft function is not disengaged by display lamp 38 is made liquid crystal indicator etc.
Below, the heading code authentication procedure of being undertaken by engine control unit 22 according to the flowchart text of Figure 10.
In the anti-joyride device 18, in the processing of the diagram of circuit of Fig. 8 and Fig. 9, the heading code ID1t of ignition key 14 checks successfully back (step S24:YES), when ignition lock 26 is placed in igniting control position (step S26:YES), to engine control unit 22 supply capabilities, carry out the diagram of circuit of Figure 10 by storage battery 27.
Engine control unit 22 after the initialization is in step S52, by timing time is 2[s] IGN ON time meter (counting machine) pick up counting, in the process of the processing of carrying out step S53, S54, S55 repeatedly, in the specified time that picks up counting from IGN ON time meter (above-mentioned 2[s]), when in step S54, receiving hatted code by order wire 16 from anti-joyride device 18 sends when requiring signal or the 2nd heading code to send to require signal, in step S71, the 2nd heading code ID2 is read and sends to anti-joyride device 18 by order wire 16 from storage part 62.
In addition, when in step S53, receiving hatted code in the specified time that picks up counting from IGN ON time meter sends when requiring signal, in step S56, random number takes place by random number generator 65, and it is sent to anti-joyride device 18 by order wire 16 as hatted code, and in step S57, be hatted code R with the random number of aforementioned generation and be stored in the function f (A, x) that the 2nd heading code ID2 substitution in the storage part 62 stores by storage part 61 computing function value f (ID2, R).And the function f (A, x) and the above-mentioned function f (A, x) that is stored in advance in the anti-joyride device 18 that are stored in advance in the engine control unit 22 are same functions.
Thereafter, when in step S58, S59, in the specified time that picks up counting from IGN ON time meter, receive result of calculation V (V=f (ID2 from anti-joyride device 18, R)) time, in step S60, to the functional value f (ID2 that receives, R) with the functional value f (ID2 that oneself calculates, R) check and judge whether unanimity, under the situation of unanimity, in step S61, send the 2nd heading code OK signal to anti-joyride device 18, the 2nd heading code ID2 that expression stores respectively is consistent, thereby in step 62, driving engine can be worked.In this case, after the timing of step S52 began, if ignition lock 26 is returned back to the starting position, driving engine was started by ignition device 71 and Fuel Injection Device 72, then ignition device 71 and Fuel Injection Device 72 work on, and driving engine works on.
Relative therewith, when in step S60, drawing inconsistent judged result, in step S63, S64, send the 2nd heading code NG signal to anti-joyride device 18, represent that the 2nd heading code ID2 is inconsistent, and driving engine can't be worked.Therefore, if driving engine becomes mode of operation later at step S52, then, the work of driving engine is stopped by driving engine can't be worked.
Promptly, in the diagram of circuit of above-mentioned Figure 10, under following 3 kinds of situations, if after the timing of step S52 begins, ignition lock 26 returns back to the starting position, and driving engine is started by ignition device 71 and Fuel Injection Device 72, and driving engine is stopped, and in step S65 by display lamp 38 display abnormality states, the operation of termination routine.The the 1st: among step S53, S54, the S55, under the situation that the transmission that does not receive hatted code R at the appointed time requires or the transmission of the 2nd heading code ID2 requires, the the 2nd: in step S58, S59, after ignition lock 26 is placed in the igniting control position, do not receive at the appointed time under the situation of result of calculation V, the the 3rd: in step S60, S63, under the situation checked of the 2nd heading code ID2 for NG.And after being judged as of step S55, S59, S60 negated, even ignition lock 26 is returned back to the starting position, driving engine also can't start.
As described above described, above-mentioned anti-theft system 10 has: anti-joyride device 18, its remote-control key 12 that will store the 1st heading code ID1r wirelessly is connected with the ignition key 14 that stores the 1st heading code ID1t, and stores the 1st～the 3rd heading code ID1 (ID1r, ID1t), ID2, ID3; Engine control unit 22, it is connected with anti-joyride device 18 by order wire 16, and stores the 2nd heading code ID2; The 3rd device 24, it is connected with anti-joyride device 18 by order wire 16, and stores the 3rd heading code ID3.
The anti-joyride device 18 of Gou Chenging has like this: permitting mechanism (mainly bringing into play the function of the step S4 of CPU60), this mechanism is checked the 1st heading code ID1 (ID1r, ID1t) that sends from carrier (remote-control key 12 or ignition key 14), and to checking from the 3rd heading code ID3 that the 3rd device 24 receives by order wire 16, then according to the checked result of the 1st heading code ID1 (ID1r, ID1t) and the 3rd heading code ID3, permit the 2nd heading code ID2 login or be updated to anti-joyride device 18 or 22 kinds of engine control units; When consistent mechanism's (mainly bringing into play the function of the step S9 of CPU60), this mechanism permit the 2nd heading code ID2 login or upgrade at above-mentioned permitting mechanism, make the stored information of anti-joyride device 18 and engine control unit 22 consistent about the 2nd heading code ID2.
Like this, when changing anti-joyride device 18 or engine control unit 22,18 pairs of anti-joyride devices are from the 3rd device 24, i.e. configuration onboard, the storage device that is connected and stores the 3rd heading code ID3 by order wire 16 and anti-joyride device 18, the 3rd heading code ID3 that sends, check with the 3rd heading code ID3 in the storage part 53 that is stored in anti-joyride device 18, this checked result is login or updating device 18 for being consistent, the necessary condition of the information of relevant the 2nd heading code ID2 that stores in 22, so, if the third party only changes the outfit cut-and-dried carrier (remote-control key 12 or ignition key 14) and anti-joyride device 18 on car body, the checked result of the 3rd heading code ID3 is inconsistent, the judgement of step S4 is false, therefore can not make the information of the 2nd heading code ID2 consistent, so improved theftproof performance.In addition, when the information that makes the 2nd heading code ID2 just when the user is consistent, just need not as conventional art, to wait for fixing time of rule, thus more convenient.
In the case, by be provided for detecting be configured in car indoor, by the processing switch 44 of the operation input of the operating portion of manual handle, when the information of login or relevant the 2nd heading code ID2 of renewal, need be as the weighting important document in the operation input of the operating portions such as drg of parking of the indoor setting of car, therefore can prevent that vehicle do not known third party's theft of this predetermined operation input, further improve theftproof performance.
Because what carry out as park drg or the brake pedal of operating portion is that braking is handled, it is the processing that vehicle is stopped that braking is handled, thereby vehicle can not move, and this has further improved theftproof performance.That is, when human desires was hatched a sinister plot to vehicle, aforesaid operations was to make the operation that vehicle can't moving direction, so theftproof performance is higher.
By being installed in, the 3rd device 24 is difficult to the position of pulling down from vehicle, for example it is installed in the inboard of the instrument assembly of being installed on the instrument carrier panel 70 36, promptly, do not pull down in the space 78 that gauge panel 74 and instrument assembly 36 just can't pull down it, or itself and fuse box 82 installed integratedly, all do not pull down in the space 88 that electric wiring 84 just can't pull down it, because it is very difficult to its dismounting, therefore it is pulled down and need spended time, and after it is pulled down again assembling also need the more time, this has further improved theftproof performance.Because proper user does not need to pull down the 3rd device 24, in addition since the 3rd device 24 to be the probability of its fault of storage device minimum.In fact, because login, renewal operation are to be undertaken by 1 order wire 16 that is connected with the 3rd device 24, can't obtain the 3rd heading code ID3 that is stored in the 3rd device 24 with cut-and-dried ignition key 14 of the third party of malice and anti-joyride device 18, can't login.So theftproof performance height.
In addition, the present invention is not limited to above-mentioned embodiment, can take various formations according to the content of putting down in writing in this specification sheets certainly.
For example, in the above-described embodiment, in the code authentication of anti-joyride device 18, also need the 3rd heading code ID3, but also variable the 3rd heading code ID3 (with step S28, S29, the S30 deletion of Fig. 8) etc. that more in the code authentication, do not need.
